TR1 - 8/10, never completed, but I'll make an estimate
TR2 - 7/10, still incomplete...noob...
TR3 - 9/10, my fave! :D
TR4 - 8/10, beautiful but hard
TR5 - 7/10, not as bad as people make it out to be
AOD - 7/10, same as above, but Kurtis and the ape-like speed loses points :p
TRL - 5/10, I'll rate it half - haven't played it yet, and I'm in no rush. :o
